Which kernel version do you use?
The default switches to s2idle based on FADT flag and _DSM on relative new kernels.
Most systems preload with Windows 8.1 should default to use s2idle.

If the system defaults to use S2I, then it’s better to stick with it.
Lots of ODM/OEM don’t really test S3.

I don’t think it’s possible.
